One thing I would say, though, is that if CFE training truly can get you to finish an ultra/ironman in a time that isn't completely embarrassing in 6-8 hours per week, I think that sounds like a very good thing for a recreational amateur. The status quo is to get divorced to support your ultra habit unless your partner really likes chafed nipples and black toenails.

No doubt, and if that was what the CFE marketing actually said, cool. Whether it's true for someone who hasn't already put in the miles is a different question.

But CFE says you can get competitive in 6-8 hours/week, and that's a shit from a totally different breed of bull.
